I'm using Gunslicks version of wipe-out. To make the simple process of applying it even tidier, I inserted a short piece of 1/4" vinyl tubing like that used on aquarium air pumps into the tubing that came with the cleaner. I stand my guns muzzle down on a rag, insert the extended tube down into the chamber as far as it will go and give it a squirt or 2 until I notice it seeping from the muzzle end. Then I'll back the tubing out of the barrel/chamber and look to see if the chamber area full of the foam, it not, it gets a short squirt of the foam too. Leave the action open, gun resting muzzle down and go do something else for a while. No fuss, very little mess.
